FEEPS Data

For more complete examples, see the FEEPS crib sheets located in the /projects/mms/examples/ folder.

Examples

Electron Data

To load and plot the MMS1 FEEPS electron data on March 7, 2016:

MMS> mms_load_feeps, datatype='electron', trange=['2016-02-15', '2016-02-16'], probe=1, data_rate='srvy'

MMS> tplot, 'mms1_epd_feeps_srvy_l2_electron_intensity_omni_spin'

Ion Data

To load and plot the MMS1 FEEPS electron data on March 7, 2016:

MMS> mms_load_feeps, datatype='ion', trange=['2016-02-15', '2016-02-16'], probe=1, data_rate='srvy'

MMS> tplot, 'mms1_epd_feeps_srvy_l2_ion_intensity_omni_spin'

Quicklook Plots

To create FEEPS quicklook plots, see the crib sheet: mms_load_feeps_crib_qlplots.pro

MMS> .run mms_load_feeps_crib_qlplots

FEEPS Sector Spectrograms

Examples

Sector-Time Spectrograms, No Sun Contamination Removed

To create sector spectrograms of FEEPS data on January 20, 2016:

MMS> mms_load_feeps, trange=['2016-01-20/19:50', '2016-01-20/19:55'], probe=1, data_rate='brst', level='l2', /time_clip

MMS> mms_feeps_sector_spec, probe=1, data_rate='brst'

MMS> tplot, ['mms1_epd_feeps_brst_l2_electron_bottom_count_rate_sensorid_3_sectspec', 'mms1_epd_feeps_brst_l2_electron_bottom_count_rate_sensorid_4_sectspec',
